Coding of reaching in 3-D space [PDF]

, 2013
Many psychophysical studies suggest that target depth and direction during reaches are processed independently, but the neurophysiological support to this view is so far limited.

Continuous Adaptive Finite Reaching Time Control and Second-Order Sliding modes [PDF]

, 2013
This paper focuses on the design of adaptive finite reaching time control for first- and second-order dynamic systems with perturbation terms given in a regressive form. The uncertainties considered here are assumed to be bounded with unknown bounds. The

Multiple parietal reach regions in humans: cortical representations for visual and proprioceptive feedback during on-line reaching [PDF]

, 2009
Reaching toward a visual target involves at least two sources of information. One is the visual feedback from the hand as it approaches the target.

Stimulus-Response Compatibility effect in the near-far dimension: A developmental study

Frontiers in Psychology, 2016
The present study investigates the developmental aspect of stimulus-response compatibility effect in 8 to 11-years-old children. The task consisted in manually responding to the colour of a pawn presented on a chessboard at different distances.

An investigation of the neural circuits underlying reaching and reach-to-grasp movements: from planning to execution.

Frontiers in Human Neuroscience, 2014
Experimental evidence suggests the existence of a sophisticated brain circuit specifically dedicated to reach-to-grasp planning and execution, both in human and non human primates (Castiello, 2005).

Visually guided reaching depends on motion area MT [PDF]

, 2007
Visual information is crucial for goal-directed reaching. A number of studies have recently shown that motion in particular is an important source of information for the visuornotor system.

Mini-max feedback control as a computational theory of sensorimotor control in the presence of structural uncertainty

Frontiers in Computational Neuroscience, 2014
We propose a mini-max feedback control (MMFC) model as a robust approach to human motor control under conditions of uncertain dynamics, such as structural uncertainty. The MMFC model is an expansion of the optimal feedback control (OFC) model.

Unlearning versus savings in visuomotor adaptation: comparing effects of washout, passage of time and removal of errors on motor memory

Frontiers in Human Neuroscience, 2013
Humans are able to rapidly adapt their movements when a visuomotor or other systematic perturbation is imposed. However, the adaptation is forgotten or unlearned equally rapidly once the perturbation is removed.

A Modified Reach-to-Grasp Task in a Supine Position Shows Coordination Between Elbow and Hand Movements After Stroke

Frontiers in Neurology, 2019
Objective: A modified reach-to-grasp task has been developed for the purpose of investigating arm-hand coordination in a supine position in the functional magnetic resonance imaging environment.
